Narrative:

Departing maf. We aborted our takeoff due to a E2 automatic takeoff thrust ctt system, no margin. We ran our checklist and contacted moc, who recommended flight crew placard the automatic takeoff thrust ctt system inoperative and continue with a T/O-1 takeoff. On the T/O-1 takeoff, we aborted the takeoff due to engine #2 over temperature and returned to the gate. We notified dispatch and moc. The flight was cancelled.
